Multi-Point Odor Monitoring and Sampling System

How to detect?

Odor monitoring device
High sensitivity hot-wire semiconductor sensor
Humidity, Hydrogen, Methane….won't be the interference during the detection
Sensor can only detect the odor compound
Sensitivity Graph
Temperature and Humidity Test
How to monitor and sampling?
Air sampling method
Use vacuum method to prevent contaminate in sample flow path.
Sampling can be trigger by high concentration or remote start by monitoring software.
Each station can equipped two tedlar bags or two canisters.
( Using tedlar bag or canister should confirm with customer before place order )
When the first bag begin to sampling, it must wait at least 60 second to start bag2.
